Internal summing of the Y and C inputs is performed to produce the composite video output. The luminance (Y) input is clamped at 1.25 V and amplified 6 dB to produce 2 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. The internal 1.5 k SAG function resistor provides gain compensation for low frequency signals. The chromanance (C) input is biased at 2.0 V and amplified 6 dB to produce 1.3 VP-P (typical) into a series 75 Ω resistor and 75 Ω cable load. During standby (Pin 5 grounded), the TK15400 consumes only 113 µW of power. Nominal power dissipation (no input) is typically 168 mW. The TK15400M is available in the SSOP-12 Surface Mount Package.
